Explain how the quotient of powers was used to simplify this expression.

5 to the fourth power, over 25 = 52

a. by simplifying 25 to 52 to make both powers base five and subtracting the exponents

b. by simplifying 25 to 52 to make both powers base five and adding the exponents

c. by finding the quotient of the bases to be one fifth and cancelling common factors

d. by finding the quotient of the bases to be one fifth and simplifying the expression
